In most cases, you do not need to keep the tap running constantly when using a pressure washer. Pressure washers are designed to generate high-pressure water streams that can efficiently clean surfaces such as driveways, decks, and vehicles. Here's how it generally works:
Priming the pressure washer: Before you start using the pressure washer, you will need to connect it to a water source (usually a standard garden hose) and turn on the tap to fill the machine's water reservoir or pump system. Once the water flows through the pressure washer and the air is purged from the system, you can turn off the tap.
Using the pressure washer: After priming, the pressure washer is self-sufficient and recirculates the water within its system. When you squeeze the trigger on the spray gun, the machine's pump pressurizes the water, which is then forced out through the nozzle at high pressure. The continuous flow of water through the pressure washer's system is what enables it to work effectively.
Shutting down the pressure washer: When you're done using the pressure washer, you can release the trigger on the spray gun, and the machine's pump will stop pressurizing the water. At this point, you can turn off the pressure washer and the tap.
It's important to note that some pressure washers may have specific instructions from the manufacturer regarding water supply, so it's always a good idea to refer to the user manual for your specific model. Additionally, some pressure washers, particularly those with special features like detergent tanks or adjustable pressure settings, may require different procedures for water supply. Always follow the manufacturer's guidelines to ensure safe and proper operation of your pressure washer.
